WINDOW ENVELOPE Elmer G. Overly, Greensburg, Pa.

Application February '29, 1932, Serial No. 595,704,

4 Claims.

This invention relates to window envelopes and has for an object to contrive an inexpensive envelope construction adapted to receive a principal enclosure and also to receive. and accurately lo cate with reference to the window a smaller addressed enclosure, while providing a common postal inspection flap for permitting access to both enclosures.

Other objects and advantages will hereinafter 1 10 appear.

' In the drawing forming part of this specification,

Figure 1 is a plan view of the lining side of an envelope blank having a partition sheet aflixed l6 thereto, the illustrated parts being adapted for manufacture into an envelope embodying the invention; and

Figure 2 is a rear view showing the completed envelope with enclosures contained in it and with the inspection flap pulled out to give access to the enclosures.

The envelope comprises a body portion 1, a back flap 2, and flaps 3 and 4, and a sealing flap 5. It also comprises a partition sheet 6. The body 26. portion has a window opening 7 provided in it.

The partition sheet 6 is secured to the body portion by stripes 8 and 9 of adhesive which are quadrangularly related to one another. The partition sheet 6 and the body portion 1 jointly form a pocket for receiving an addressed enclosure substantially smaller than the body portion of the envelope. The adhesive stripes 8 and 9 form two of the boundaries for the pocket, and control the dimensions of the pocket. The end flap 4 and the back flap 2 are folded over and are united, one to the other, by an adhesive stripe 10.

The back flap 2, in conjunction with the body portion 1, forms a boundary for the main enclosure receiving space corresponding to the pocket boundary formed by the adhesive stripe 8, and

the end flap 4, in conjunction with the body portion 1, forms a boundary for the main enclosure receiving space corresponding to the pocket boundary formed by adhesive stripe 9.

The end flap 3 is folded in simultaneously with the end flap 4 but is not adhesively united to the back flap 2. The end flap 3, in conjunction with the body portion 1, forms a common boundary for the main enclosure receiving space and for the pocket.

The sealing flap 5 is provided with adhesive 11. After both enclosures have been inserted in the envelope the adhesive 11 is moistened and the sealing flap is folded over against the back of the envelope. The adhesive 11 is disposed to engage end flap 4 and back flap 2 but to escape engagement with end flap 3. The sealing flap forms a common closure and boundary for the main enclosure receiving space and for the pocket. The end flap 3, being unconnected to the other flaps, may be pulled out as shown in Figure 2 to permit access to both enclosures. The end flap 3, therefore, forms a common postal inspection flap for the main enclosure receiving space and the pocket.

The envelope described may be used for a variety of purposes. For example, the main enclosure 12 may be a pamphlet of trafiic regulations suitable to be sent to new drivers of automobiles, while the addressed enclosure 13 may be a beginners permit card. The envelope can also be used for mailing courtesy cards together with sales letters, or lodge cards together with collection or subscription letters. These uses, however, are cited merely by way of illustration since the envelope is adapted for use whenever it is desired to send a main enclosure and a smaller addressed enclosure of the same postal class in a single envelope.

I have described what I believe to be the best embodiments of my invention. I do not wish, however, to be confined to the embodiments shown, but what I desire to cover by Letters Patent is set forth in the appended claims.

I claim:

1. In an envelope, in combination, a body portion having a window opening in one corner thereof, an end flap and a back flap adhesively united to one another and, together with the body portion, forming boundaries for the main enclosure receiving space of the envelope, a partition sheet adhesively secured along two quadrangularly related margins to the inner face of the body portion but unconnected elsewhere, said partition sheet dividing ofi from the main enclosure receiving space of the envelope a pocket located in the window area for an addressed enclosure smaller than the envelope, a closure flap adapted to be sealed against said side and end flaps and to form a third boundary for the main enclosure receiving space and for the pocket, and a postal inspection flap disposed over the partition sheet and removably received beneath the back and closure flaps and forming a fourth boundary for the main enclosure receiving space and for the pocket.

2. In an envelope, in combination, a body portion having a window opening therein, a back flap, end flaps, a sealing flap, said body portion and flaps defining a main enclosure receiving space, a partition sheet, adhesive uniting the partition sheet to the body portion along two quadrangularly related stripes to provide two side boundaries for a small pocket in the window portion of the envelope, the sealing flap in conjunction with the body portion forming a common boundary for the main enclosure receiving space and for the pocket, sealing adhesive on the sealing flap arranged to engage the back of the envelope but to escape engagement with one of the end flaps, said end flap forming with the body portion a common boundary for the main enclosure receiving space and for the pocket, and being unconnected to the other flaps to permit access to said space and pocket.

3. In an envelope, in combination, a body portion, a partition sheet adhesively united to the body portion for dividing the enclosure receiving space into a main space and a pocket, an inspection flap forming a common boundary for the main space and the pocket, and a'sealing flap forming a common boundary for the main space and the pocket, the pocket being disposed between the partition sheet and the body portion, and the body portion having a window to expose an address on an enclosure received in the pocket.

4. In an envelope, in combination, a body portion, a partition sheet adhesively united thereto for dividing the enclosure receiving space into a main space and a pocket smaller than the main space, a sealing flap, andan inspection flap said pocket being open for access both from said main flap and said inspection flap, the body portion having a window to expose an address on an enclosure received in the pocket.
